DCS/CTCSS Rapid Decode - Instantly Detects and Displays the Subaudible Tone So You Can Quickly Determine the System Settings.

The way scanner listeners make use of this feature it to narrow down who you want to monitor on a given frequency.

Lets say for example you live in town A, and your fire department uses 151.500MHz, with a CTCSS tone of 123.0, and very close to you in town B, the local tow truck service also used 151.500MHz, with a CTCSS tone of 88.5. If you did not enable the CTCSS feature, you would be hearing communications from both your fire department, and the tow truck service in the neighboring town, and they would often interfere with each other.

Say you only want to listen to your fire department, and ignore the tow truck service in the neighboring town. By enabling a CTCSS tone setting of 123.0, you would lock-out all transmissions from the towing service, and only hear your local fire department.

DCS works in a similar manner, but is a newer digital method.

The bottom line is using CTCSS, or DCS, allows you to hear less, not more, which is sometimes desirable.
